cuff without detaching the fastener from thev cui, and .which 'is readily restored to normal position by merely pinching together the button heads of the fastener.

More specifically, it has for its object a fastener of this type consisting of a main link which normally extends lengthwisevbetween flaps or sides of the cuff, additional links pivoted to opposite ends of the main link, and normally overlying the main link with-their free ends adjacent each other, andbuttons having shanks pivoted to the free ends of the additional links,

together with means havingy a snap action for holding the additional links in their normal position overlying the main link, when the culi is closed, the links being unlocked by merely presstogether, and when the links the cuff separated, position between the margins of the cuff, and at the same time, the additional links swing in opposite directions into a position in which they are nearly lineal extensions of the main link, and the shanks. of the buttons extend into lineal extensions of the additional links, thus affording a wideopening of the cuff.

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

1n describing this invention, reference is had to the accompanying drawing, in which like characters designate corresponding parts in all the views.

Figurel is a side elevation on an enlarged scale of this fastener applied to a cuff, the contiguous portion of which is shown in section.

Figure 2 is a plan view on an enlarged scale of the fastener showing the parts in their normal position,

Figure 3 is a plan view showing the parts in their extended position.

Figures 4 and 5 are sectional views on lines 4--6 and 55, Figure 2.

The link l is provided with Stop shoulders I4 and l5 for limiting the-collapsing movement of the links 2, 3 respectively on the main link, v

limit the movement of the link 3 after it has slightly over-run its normal position in interlocking engagement with the pivot I0 between the shank 8 of the button 6 and the link 2, so that there is a clearance at the unlatching when the bottons are pinched toward each other. Also, suitable stop shoulders I3 and I1 are provided for limiting the'outward extending movement of the links 2,- S'beiore the links enter a dead center line L passing lengthwise of the main link I through the pivot points, 4, 5.

The shank 8 of the button 6 for the link 2 is formed with a cam surface 8a up which the end of the link 3 rides when the buttons are pinched toward each other, this raising the extension 3f'L up from behind the extension 2a and out of interlocking engagement therewith as shown in Figure 5 The clearance I5a permits this unlocking movement. When the parts are in the position illustrated in Figure 5, the link 3 is pressed against the stop shoulder I5 and is under tension and when the parts are quickly pulled apart, the tension is overcome andthe extension 3a is moved beyond its interlocking position with the extension 2a. and allows the links to open.

In operation, the buttons are first applied to opposite flaps ofthe The links 2 and 3 y are foldable in opposite directions aboutthein into extended f position link, as 'the link 3, has its pivot a corre- 2a on .f the link and inter?` locks therewith when the links 2; 3 are innormalj link, and isformedK material to press its extension 33A flatwise toward the extension-2eL of the linkV 2 2a, 3a are.

A cul fastener additional links pivoted to the end of one additional link overlapping the end of the other,

tensioned to press toward the main link.
